What It Comes WithThe quick start guide that comes with it is in Chinese, and as of now, there aren’t any guides in English.The Mijia 4K also doesn’t come with any extra accessories such as mounts or waterproof housing, which is one of the main drawback of this.
Optional accessoriesHowever, there are many external accessories that you can buy. Although as of now, they aren’t any original accessories out for sale yet, there are a couple of third parties accessories you can buy.Anyways, below are some of the accessories that work together with the Mijia 4K Action Cam.The gimbal is pretty expensive when compared to the camera but the price is still really reasonable for a gimbal with this quality.Furthermore, the gimbal is only compatible with the Mijia 4K, which further limits its versatility.The gimbal works together with the Mijia 4K really well and once it’s connected, you can directly control and charge the camera such as starting and stopping recording, exposure settings, from the gimbal. Furthermore, it is also able to charge it using the gimbal’s battery.Till this date, I’d still think the Mijia 4K has the best, most integrated action camera gimbal, amongst others such as the Yi Gimbal.
Waterproof Case – 40mI actually expect a waterproof case or a protective housing to come with every action camera but apparently this isn’t the case for the Mijia 4K.As of now, there is only 1 official one selling at Gearbest and it does seem to be very well-thought of and good quality.Buy Here (Official):

Charging – Solid Red; Fully Charged – No LightHigh Battery Level: Green; Medium Battery Level: Orange; Low Battery: Solid RedTop Indicator has only 1 function which is to indicate that it is recording.Recording: Blinking Red; Successful video saved: Rapid Blinking Red
PortsThere are 2 ports.The Micro-USB port is used to either transfer media to your computer or for charging.This port is also protected by a door which can be easily slid close or open to access the port.The other one is the Micro-SD card slot which is under the battery cover, beside the battery.
MountingThe only way to possibly mount this camera, as of now, is using the ¼: thread tripod bush. This can be mounted onto almost all of the selfie sticks and tripods out there, which makes it convenient and easy to mount.
NavigationI found the settings are very neatly designed and navigating around is rather straightforward too.
Quick MenuIf you swipe down, you’ll be able to access the quick menu.
SettingsThere are different settings for each mode and an additional one for the device.

- Slow down by 2x (1080p 60fps): Final Output: 1080p 30fps
Shooting ModesThere are a total of 9 shooting modes, which includes everything and I mean everything, that you’ll need! All you need to switch modes is a swipe and a tap.
- Video: Basic Video Recording
- Time-Lapse Video: Automatically creates time-lapse video
- Slow Motion: Automatically creates slowed down video
- Loop Recording: Useful for dash cams where if storage is full, it’ll overwrite oldest clip and continue recording
- Video + Photo: Takes a photo at a set interval, while video is being recorded. Least used mode in my opinion. (Used in comp
- Photo: To take a picture
- Timer – Takes a photo after the set duration
- Burst: Takes multiple photos quickly all at once (max: 10 pics/s)
- Time-Lapse Photo: Shoots photos at a regular set interval, which can be edited into time-lapse later on.
Unique FeaturesThe 6 axis image stabilization is powered by the Bosch BMI160 IMU, which has a 3 Axis Gyro-meter and a 3 Axis Accelerometer, allowing the camera to accurately stabilize the video without much loss in quality.
Stabilisation SamplesLet’s take a look at some samples comparing the image stabilization. As you can see from the samples above, it works very well and is definitely better than most action cams at this price point!However, having said that, a small drawback is that the electronic image stabilization only work for video resolution up to 1080p 60fps and wouldn’t work for anything higher.
Image Sensor & LensThe lens has a f/2.8 aperture and has a field of view of 145˚.On average, most action cameras have an aperture of about f/3+ and a field of view of about 170˚. Thus, using that as a comparison, the Mijia has a higher aperture which helps it shoot better in low light scenarios. At the same time, it has a narrower field of view, which means that it does not record as wide of a video and at the same time lesser fisheye distortion.
What does Aperture and Field Of View mean?Let me try my best to make this as simple as possible. In action cams, the aperture number is simply the size of the image sensor. The smaller the number after the ‘f/’ is, the bigger the aperture, hence size of image sensor is.Therefore the bigger the aperture, the more the light will get through, and hence, the better it is at low light environments.On the other hand, field of view is how wide the video is. It is measured in degrees and 180˚ means it can record everything from the left to right and 90˚ means it can only record half of that.
Image QualityThe Mijia 4K camera is capable of taking 8.3MP photos (3840 x 2160).I found the image quality is very good and sharp. Colours are also very saturated and accurate.For it’s price, I think it has one of the best photo quality I have seen and I really like it!Enjoy the samples below 🙂 .
RAW Vs JPGThis mini action camera also has the ability to shoot ‘RAW’ photos!If you are new to photography, RAW is a file format that captures all the image data recorded by the image sensor when taking a photo. On the other hand, when shooting in a format like JPEG, image information is compressed and lost, which results in a lower quality when compared to RAW photos!

Battery & ChargingShooting time – 92 Mins of 4K 30fps, 119 Mins of 1080p 60fps.You’ll need to update your camera as there were some bugs like frequent crashing in the earlier versions and the earliest versions did not have a English menu.After updating, I couldn’t find any bugs or glitches after few days of use and I’d have to say it is very stable and didn’t crash or glitch out even once.
Latest Update: 0.6.9.2576 1. Loop recording enable EIS function: only available for 1080P / 60fps and 1080P / 30fps;2. Optimize the dynamic display of the upper right corner icons in the preview interface;3. Optimize underwater white balance;
There are as far as I know, 2 ways to update.The first method, which I feel is less troublesome would be to use the MiHome smartphone app and directly update from there. Simply follow the instructions to download the update and it will do all the work for you.The second method is to download the firmware update from the MiFi forum here and copy it to your storage card. You can easily follow the steps on that forum and that’ll require a computer to work.

Verdict: Great Value For Money 4K Mini CamI’m not sure whether I can call this an action cam because action cameras are usually made for durability and endurance and this camera does not seem to fit into that category.Anyways, despite that, I feel it has very good for value money as it is able to shoot 4K recording, take ‘RAW’ images, and still include an amazing image stabilization all into this little device.Furthermore, it is neatly categorised, have tons of customisations and an appealing and unique design. And because of this, I’m definitely using the Mijia action cam as my main camera for travelling and vlogging.On the other hand, for improvements wise, I felt that they should have at least included a protective casing because without any sort of protection, the lens can get smudged quite easily and the aluminium body seems like it can also get scratched too.At the end of the day, if you’re fine with having no accessories and am thinking of mounting it on your selfie stick or tripod, I’d definitely recommend this to you because it is for sure one of the best bang for your buck action cameras out there in the market!
